most sites it is safe and they do a good job, i haven't delt with him but many roomies on here and one of my buddies had asbjoe drill a ball for them and it turned out great, get your drilling specifications and send them to him and let him know about grips and such and it is a nice way to get it done.
*Note i only use my local pro shop though..*
Oh and i almost forgot, Noy are you trying to buy another bowling ball??
